SIEECIFIGATION forming part of Letters Patent No. 552,038, datedDecember 24, 1895- Apjilication filed March 25, 1890.

To all ivhom it may concern Be it known that I, l\[0RTON G. BUNNELL,

cage, infthe county of Cook and State of Illinois, have invented acertain new and useful Improvement in Supplemental Conveyers forthefollowing is a specification.

My invention while applicable to various proved attachment to theconstruction of grading and ditching machine set. forth in Edwards,'November 27, 1888, No. 393,467.

becomes at times desirable to deliver the plow than can be. attainedwith a'singlc'machine. p

The object of my invention is to overcome by side, and while butoneisused for plowing up thesoi-l the two machines can be used conjointly forconveying and delivering the, same from the plow to a point remote fromthat \vhereat the soil is plowed-up.

ditching machine provided with my improvement. Fig. 2 represents inelevation on a larger scale the conveyor hopper or receiver. Fig. 3 is adiagram illustrating the elevatingbottom of the hopper. Fig. 4. is alongitudinal section on avertieal plane through atportion or: theconveyor and also through the hopper. Fig. 5 represents a section takenthrough a portionof the hopper on a plane transverse to the length ofthe conveyor-belt, which lat ter is partially show Fig. (3 is a plan ofthe hopper and a portio of the conveyor, and shows the conveying-aprons,which form the bottom of the main conveying belt or apron. Fig. 7 is asection taken transversely through the machine, the plane of the sectionbeing through the elevating-convcyer.

. The machine re resented in Fi s. 1 and 7 P s Serial No. 345,271. Nomodel.)

is generally similar to that described in the patenthereinbeforereferred to, and hence need not be particularly described,it'bcing' understood, however, that the plow and also"the-elevating-conveyer shown in said patent have been removed and thatan elevating-com veyerprovided with ahopper at its receiving end hasbeen substituted, so as to adapt the machine for receiving and conveyingin accordance with my improvement. ing-conveyerA is arrangedtransversely to the length ofthe machine and preferably-extends themachine so that it will incline upwardly froni its receiving end, and itis also desirably made of such'length that its delivery end shall extendout from one side of the machine,

as shown in Fig. '1.

able frame aand an endless conveying belt .or apron (1 and like theclevating-conveyer in the patent referred to, it is desirably providedwith guards aflsoas to form a passage-way whereof the upper leaf of theconveying belt or apron forms the bottom. This elevatingconveyer isprovided at its recei ving end with r a hopper B, constituting areceiver into which the soil can bedepositcd from the elevating conveyorof another machine. The casing which forms the sides of this hopper issee ured to the frame of the elevating eonveyer, and to such end Fig; 6illustrates the rear side 1) ol said casing secured to said frame oi.the eleval-i ng-conve yer by cleats or angle-iron a, which areunderstood to be bolted to the casing and frame. By such arraiigcmenthe,

elevating-convcycr is practically PlOVlilL d at one end with a hopper orreceiver. per has its bottom mainly formed by a couple Theelevat:

This hopof endless conveying belts or aprons b, which are so arrangedthat when they are caused to travel in the direction of the arrows inFig. 6 they will eonve y the soil deposited in the hop per toward anddeposit the same onto the endless belt a of the elevating-conveyer. By

. 75 The elevating-conveyor comprises a suitsuch arrangement a machinethus equipped can be driven alongside a machine provided both with anelevating-conve yer and a plow, as in said patent, so that durin goperation. the plowed-up soil will be first taken from the plow bytheelevatin g-conveyer of the machine thus furnished with. the plow andthen discharged into the hopper B, from whence it will be taken by theconveyer-belt c of the elevat' ing-conveyer with which the second.machine is supplied. I

The comparatively short conveyerbel.ts I). can be arranged. at rightangles to the line of belting a, as illustrated by the diagrammaticview, Fig. 3, or said belts b can be arranged obliquely to the line ofbelting (113.215 in Fir 6, in which'case any danger of long rods beingcaught by the corners of the-hopper will be avoided. i

The bottom of the hopper is of course open so that the two belts b and aportion of the belt of may form its bottonnend its back is also providedwith a suitable opening I)", so as to. permit the soil and other mattersdeposited therein to be carried out by the conveyorbelt a.

The short conveyor-bolts b can be driven' from the belt-roll (J at thereceiving end at the elevating-conveyor by means of link-belts, or byany other suitable gearing, the mode herein shown of operating the beltsI) being to gear-connect short rotary shafts l) with the endsat' thebelt-roll O, and connect sprockets upon said shaftssvith certainbelt-rolls f orthe belts I) by link-belts E. The belt-r0ll C can bedriven as in said patent or in any other shitable way.

From the foregoing it will be seen that the machine comprises anelevating-conveyor provided at one end with a receiver comprising ahoppencasing which is secured to a. frame a provided for the rolls ofthe belt c,/

and the short endless belts'or aprons I) which first receive the soildeposited in said hoppereffect a portion of the hopper-bottom, (see Fig,6,) and by arranging the bolts 2') Z) at cpposite ei de's of thelongitudinal middle portion of belt o the said bottom is practicallyextcndod, and furthermore, the oblong hoppercasi ng can be made muchlonger than the h'uspcn'ded in the patent hereinbot'ore referred to, andsince the receiving ondoi' the said frame will be weighted by the hoppere sing and bolts 7) Z), a stay-chain a Fig. 7, can connect said casingwith a drum or winding-rod a, which can be operated for the purpose ofadjusting the length. of chain between the rod and hoppereasing withreference to the elevation of the receiving end oi the olevatingbonveyer. With further reference to the receiving and cmiveyingbolts '1). it is understood that they are positively operated during theprogress of the machine by powertransmitting meanswhich is primarilyoperated by one oft-he wheels oi. the carriage, and that thisapplication does not comprise the receiving and conveying belts operatedsolely by the weight of the material thereon, as embodied in applicationSerialNo. 399,8Q9 of myself and Clement l5. Ilinman.

What I claim as my invention is-- A machine for service in grading andditching work, comprising a wheeled carriage, and an attachmentsupported from the-carriage and consisting of an elevating conveyorconstructed with. belt'rollsand an endless conveying belt which isdriven during the progress of the carriage, a hopper positioned at oneside of the carriage and having at its bottom a receiving and conveyingbelt arr nged to discharge onto the conveying belt of the elevatingconveyor, and gearing for driving the belt at the bottom of. the hopperfrom a belt roll of the elevating conveyor, substautially as described.
